. The above described construction is such as .will permit the plastermixture 143 placed in the box like member 110, on the movable member 121to be forced outwardly therefrom by the said movable member. which ishinged upwardly by the lever 1'16 when the said shaft 67 is rotatedmanually by the hand wheel 67 or by the electric motor 42. g

It is understood that the box like member is raised vertically so as topermit its extended lip 110 to engage or strike the laths 1423 securedto the ceiling of the room to be plastered and that my improved machineis rolled along the floor, as above set forth, during the operation ofthe operating lever, as ameans of spreading the plaster mixture.contained in "the said box like member. 1

and is provided with a handle element 152.

The latter described construction is such as will permit the container146 to be hinged out wardly by the manual movement of the handle element152. A limiting member 153 or stop is secured to the container 146 'as ameans of limiting the movement of the, lever 149.

A flexible member 154 is secured to the box like member 144 and isextended upwardly therefrom over a pulley 155 secured to the upperportion of the cross member 21. The flexible member 154 is extendeddownwardly from the pulley 155 as at 156 over the pulley 157, secured tothe box like member 144 and is extended upwardly therefrom as at 158,

The flexible member 154 is extended upwardlyfrom the pulley 161, as at 162 over the pulley 163 secured to the crossmember 21 and is further extended therefrom as at 164, and is wound orextended around the above mentioned drum tainer 146 to bespread on thewallof the room, when the said container is raised vertically by meansof pressing or pulling the handle element 152 by the operating lever 151downwardly.

In Fig. 1, of the accompanying drawing, I have shown ,a scaffoldembodying a frame like member 168 of rectangular construction,

horizontally disposed or mounted on suitable castors 169. A pair of endsupports 17 0 and 171, of a frame like construction are hinged as at 172and 173, respectively to the opposite extremities or ends of the frame168, and are held in vertically extended positions therefrom, bymeans ofangular supports 174 and 175, respectively, which are hinged asat 17 6and 177 to the end supports 170 and 171 and extend therefrom and engagein notches formed in the brackets 178 and 179 secured to the frame 168.Rectangular members 184 and 185 or boards are adapted to extendintermediate the end supports 170 and 171 andare placed on any desiredone of the cross members 186 and 187, as may be desired. Rectangularmembers 188 and 189 are hinged as at 190 and 191, respectively to theupper extremities of the end supports 170 and 171,and are held in ahorizontal extended position therefrom-by means of the supports 192 and193, hinged as at 194 and 195, respectively to the rectangular members188 and 189, and removably engage the extended elements 196 and 197 ofthe end sup-i ports 170 and 171. I

The above described construction is such as will permit plaster mixture198 and 199 to be placed on the rectangular men'ibers 188 and 189, andwhich will also permit workmen to stand on the boards 184 and 185 forthe purpose of plastering the ceiling or walls of the room with the saidplaster mixture as may be required to supplement the plastering placedon the said ceiling and walls by my improved machine.

A pair of engaging members 200 are se cured as at 201 to the end support171 and are provided with downwardly extended elements 20201extremities, preferably of ,tapered construction adapted to engage insimilar shaped openings 203 formed in the extended elements of thesupports 204 secured as at 205 to the upright member 10. The abovedescribed construction is such as will permit the scaffold to beremovably attached to my improved plastering machine for the purpose ofpermitting the scaffold to be moved along the floor with the plasteringmachine rendering same to be accessible at all times thus expedit'ingthe use of the said scaffold;
